Objectives: To test the hypothesis that the sagittal position of the anterior teeth has no effect on pharyngeal airway dimension or hyoid bone position and to investigate the influence of orthodontic retraction of the anterior teeth on each section of pharynx and hyoid position. Materials and Methods: Forty-four Class I bimaxillary protrusion adults, treated with preadjusted appliances and maximum anchorage after extraction of four premolars, were divided into two groups according to their vertical craniofacial skeletal patterns. Pretreatment and posttreatment variables were compared using paired t-test, and the relationship between pharyngeal airway size and dentofacial variables was analyzed using Pearson correlation coefficient. The changes of pharyngeal airway size and hyoid position after treatment were compared between two groups using independent t-test. Results: Upon retraction of the incisors, the upper and lower lips were retracted by 2.60 mm and 3.87 mm, respectively. The tip of upper incisor was retracted by 6.84 mm and lower incisor retracted by 4.95 mm. There was significant decrease in SPP-SPPW, U-MPW, TB-TPPW, V-LPW, VAL, C3H, and SH (P , .05). No statistically significant different changes were observed in the dentofacial structures, pharyngeal airway, and hyoid position between the two groups after the treatment. There was a significant correlation between the retraction distance of lower incisor and the airway behind the soft palate, uvula, and tongue. Conclusions: The pharyngeal airway size became narrower after the treatment. Extraction of four premolars with retraction of incisors did affect velopharyngeal, glossopharyngeal, hypopharyngeal, and hyoid position in bimaxillary protrusive adult patients.

All patient-oriented websites on dental implants scored above the recommended grade level, and majority of these sites were "difficult" in their readability. There is a dire need to create patient information websites on implants, which the majority can read.

Background: Orthodontic braces have become symbols of wealth and fashion accessories in some parts of the world. However, there is a scarcity of information about the effects of fashion braces on various aspects of quality of life. Therefore, our aim was to investigate the effects of fashion braces on oral health related quality of life (OHRQoL). Methods: A cross-sectional study was carried out with data collection from a Google form questionnaire distributed in Saudi Arabia via various forms of social media over a period of 4 months. OHRQoL was assessed using the validated Arabic version of the Oral Health Impact Profile-14 (OHIP-14) questionnaire. The fashion braces group included respondents who had braces installed for fashion purposes only. Therapeutic braces group included subjects who were wearing braces to treat any malocclusion problems. Control group included subjects who did not have any kind of braces. People who had previously completed orthodontic treatments were excluded from the study. The negative impacts were divided into seven domains and a total OHIP score was calculated. Statistical analyses and data illustration were performed with SPSS v25 (IBM, NY). Results: A total of 1141 people voluntarily participated in the study. More than 60% of the participants were in the control group while 33.7% had conventional braces for therapeutic reasons and 3.4% had fashion braces. Sociodemographic distributions varied among the groups, with the majority of the fashion braces group having education below the university level and family incomes less than average. There were significant group differences in OHIP domains. Physical pain was the most frequently reported complaint by all subjects and was the highest in the therapeutic braces group. People with therapeutic braces reported significantly higher functional limitation and physical disability than the controls. Fashion braces group reported significantly lower psychological discomfort and disability, social disability and handicap compared to control groups. Conclusions: The illustrated effects of fashion braces on OHRQoL suggest the need to study the role of social media and educate the public on the use of braces to minimize the negative effects experienced by individuals.
